Tech 2 Flashcards
What is the purpose of the HYD priority valve?
Under low system pressure, high load users are cut off
When does the fuel crossfeed valve automatically open?
In EMER ELEC CONFIG
What systems does the the HYD priority valve cut off?
Ldg gear, Emer gen, NWS (LEN)
If the Emer gen is powered by the RAT, when is it automatically turned off?
At slat extension. Can be turned back on by using MAN ON
In normal law, what is the pitch attitude limited to?
30°
If the ground spoilers are disarmed, with they function on landing?
Yes, once both MLGs down & 1 eng in Rev (other in idle)
How can fuel flow to a running eng be stopped?
Selecting eng master to OFF or pressing eng fire pb
NWS steering has no inputs from the hand wheel on ldg above what speed?
100kt (authority gradually reduced from 14 kt)
When is the alt alert inhibited?
- slats out and gr down,
- GS capture
- gr down
When the APU bleed valve PB is on, what happens to valves in AIR SYS.
- Eng bleed valves close
- x-bleed valve opens
- APU bleed valve opens
What is the risk of holding the IDG disconnect button for more than 3 secs?
May damage the disconnect mechanism
What could trigger a spurious FWD CRG SMOKE warning on the ground?
Insecticide spraying or a very humid day
What do the two channels of the SFCC do?
One for flaps, other for slats
If one SFCC fails, how will this effect flap/slat operation?
Flaps and slats will move at half speed
With high speed protection activated at 45° AoB what bank angle will the aircraft roll to with no stick input?
0° - wings level (in normal law would usually be to 33°)
What slats have anti-ice availible?
The four outboard slats on each wing
Where is the neg relief valve?
Aft and below the L1 door
Where is ILS 1 information shown?
PFD 1 and ND 2
What triggers probe heat to come on automatically during startup?
At least one eng running
can be selected to ON to operate immediately on the O/HD panel
What height can APU bleed be used up to in the climb?
FL250
If wing anti-ice is selected on prior to TO what will happen?
The valves will open for only 30 secs for a test, they will reopen on lift off
How does airbus order the various systems during the troubleshooting phase of the SMOKE/FUMES drill?
From the most probable to the least probable
Why will the aircraft often be left or right of runway centreline after crosswind landing
LLZ aerial in aircraft nose, therefore in crosswind ldg centre of aircraft not lineup up with runway (esp with residual crab angle on ldg)
